I see the loongarch-next HEAD has been updated and it's now purely arch 
changes aside from the two trivial irqchip cleanups. Some other changes 
to the v11 patchset [1] are included, but arguably minor enough to not 
invalidate previous Reviewed-by tags.

After some small tweaks:

- adding "#include <asm/irqflags.h>" to arch/loongarch/include/asm/ptrace.h,
- adding an arch/loongarch/include/uapi/asm/bpf_perf_event.h with the 
same content as arch/arm64's, and
- adding "depends on ARM64 || X86" to 
drivers/platform/surface/aggregator/Kconfig,

the current loongarch-next HEAD (commit 
36552a24f70d21b7d63d9ef490561dbdc13798d7) now passes allmodconfig build 
(with CONFIG_WERROR disabled; my Gentoo-flavored gcc-12 seems to emit 
warnings on a few drivers).

The majority of userspace ABI has been stable for a few months already, 
after the addition of orig_a0 and removal of newfstatat; the necessary 
changes to switch to statx are already reviewed [2] / merged [3], and 
have been integrated into the LoongArch port of Gentoo for a while. Eric 
looked at the v11 and gave comments, and changes were made according to 
the suggestions, but it'd probably better to get a proper Reviewed-by.

Among the rest of patches, I think maybe the EFI/boot protocol part 
still need approval/ack from the EFI maintainer. However because the 
current port isn't going to be able to run on any real hardware, maybe 
that part could be done later; I'm not sure if the unacknowledged EFI 
bits should be removed as well.

Arnd, what do you think about the current branch's status? Do Huacai 
need to send a quick final v12 to gather tags?
